It will be evident that myinvention-can be utilized in gang plows hav ing any desired number "of plow bodies and consequently I do iiot l-imit myself to the number of plow bodies or other furrow openers shown, or to the particularconstruction of the plow to which my inventionis applied.

I have shown a frame comprising beams 1 and 2 carrying on their rear end-s plow bodies and 4. The beams 1 and 2 are spaced apart and secured'togethe-r by a rear brace'fi, a center brace-6, and a forward brace 71- To the forwardze'nds-ef the beams 1 and Q/ls connected adra-w bane; through which, by "suitable devices, the plovvi'is' attached to a drawing power.

Tlievrear 10f the plow is supportedby a furrow wheel supported on a'erank'axle l0 and havingan upstanding spindle-11 which 'isjournal-ed in a'bearingw. On the beam Q'issecuredabracket -13. A Ushaped link 14 has one of its arms pivotally jour naled entire lower portion of the hearing lil,

ed afurrow wheel 22 at a right angle thereto, asleeve in and its second armpivotally-supported on 'the lower portion of the bracket-13. Rockably supported'on the bracket 13 is a mernbee 15 vwhich is alsopivotally-connected to the upper portion ofthe-bracket 13. A lever i6 is pivotally "supported, "intermediate its length-fen the upper end of the bracket lii,

and carries, on 'its lower end, a roller '17 "whicl operates against-thelower face of an arm 18 preferably integral with the member 15. A rod 19 connects the upper end of the lever 16 with the "forward lifting mechanism,

as will be hereinafter described, so that the front and-rear-of the plow are raised simultaneously.

Rockab'ly journaled frame is a transverse crank axle 20 having a landward downwardly extending portion or crank arm a terminating in a spindle on which ismOunteda landwheel 21, and afurrowward downwardly extendingportion 7) terminating in a spindle on which is mount- R-igidly secured on the landwheel 21 is a gear 23 th'rough'which the traction powenof the wheel is trans- -1nitted to the raisingand lowering mecha- The arcuate portion is concentric with a piv 0t pin or bolt 26 lined in an enlargement of the rim. The part- 22 has extending upwardly and rearwardlytherefrom, at an obtuse angle, an arm 27 havinga lug 28, 9

intermediate its length, to which .the forwvaf-dendef the rod '19 is pivotally con- ;nected; 5

Rigidlysecu-red on the beam 2 is bracket 29, and pivota'lly' mountedon the forward upper-end thereof is a sleeve-30 threaded interiorlyfor reception of a screw shaft 31. A tabular member 32 overlaps-the part 2 of the"bracket c* and is pivotally secured thereonloy the bolt '26 which extends through an orifice 83 in the member '32. Preferably and eiten'ding integi'ahwith the in'ein'ber 32,

'whichlis journal'ed a'ishaft 35 on the plate end of which is non-rotatably secured a pin-' in bearings'on the loosely mounted on a stub shaft 38 on the member 32.

The pinions 36 and 37 are equidistant from the pivot of the member 32 and are mounted respectively on opposite sides thereof; consequently any movement of the member 32 on its pivot will cause a concentric movement of the pinions 36 and 37, and at the same time the screw 31 will be rocked on its pivotal support on the bracket 29, as will be hereinafter described.

On the opposite end of the shaft is rigidly secured a hollow frnstrum 39 having a bevel gear 40 tlorming its edge; a split yoke ll, at its lower end embraces the sleeve 34, and is held between collars -f2 preferably integral with the sleeve 34-. The upper end of the yoke all embraces the screw shaft 31, and in its central portion is formed a socketto receive the lower end of the screw shaft 31, which at this point is provided, preferably, with ball bearings as shown in dotted lines in Figures 5 and 6. l Vithin the yoke 41:1 a bevel pinion l3 is rigidly secured on the screw shaft 31 and meshes with the bevel gear 4L0. The parts of the .yoke d1 are bolted together as shown. By this construction when the member 32 rocks about the pivot 26 the shaft 35 and the parts connected with it, including the gear 40 and the inner end of the yoke ll, will move with it, thereby rocking the screw 31 so that it maintains its radial position with relation to the gear 40 and the pinion d3 is held properly in mesh with said gear. in arm as extends from the sleeve 34: and is securely bolted to a projecting portion d5 of the part 22 of the bracket 0.

A plate 46 is pivotally secured on the member 32 by a bolt 47 which is lined in an orifice 48 in the member 32, and a Similar plate 49 is also pivotally se aired on the member 32 by a bolt 50 which is tired in an orifice 51. in the member The plate 4-9 partly overlaps the plate ll; and is provided with a notch 52 which registers with a similar notch in the plate 4:6. In the plate 46, at the opposite end from its pivot, is a slot 53 and a similar slot 54!: is provided in the plate 4-9. The slot 53, in the plate ;:6, is concentric with the pivot of the plate a9, and the slot 54, in the plate 49, concentric with the pivot of the plate d6.

Secured on the side of the tabular member 32, toward the beam 2, are lugs 55 and 5h perforated to permit longitudinal movement of a latch 57 mounted therein. One end of the latch 57 is bent to extend through a slot 58 and engage with the notches 52 in the plates 46 and .1.9, the opposite end of the latch is enlarged as shown and is adapted to engage with. either of the notches L5 in the part- 2 l; a coil spring 59 surrounds the shank of the latch and exerts its expansive force between the lug 55 and the enlarged end of the latch. A guide block 60 is secured to the latch 57 and is movable therewith against the adjacent surface of the member 32.

A link 61 is bent at one end to extend through the slots 53 and 5a in the plates 46 and 49 and is held therein by a pin or cotter; the opposite end of the link 61 is pivotally connected to an arm 62, which is preferably inte 'rzd with a sleeve 63, and extends forwardly and downwardly from the sleeve. The sleeve (33 is rockably supported on the upper end of the arm 27 by a bolt or pin (3% and is secured thereon by a cotter. EX-

tending upwardly from the sleeve 33, and

preferably integral therewith, is an arm (36 having a rod 57 hooked to the upper end and extending forwardly where it is sup ported and movable freely in a bracket 68, the latter being secured on standard 69 mounted on the beam 2.

As more clearly shown in Figure 1 an arm 70 extends landwardly from the bracket 29 and mounted thereon is a stop 71 having a slot 72 through which extend bolts 73 securing the stop in place. By loosening the bolts 73 the stop is adjustable longitudinally in either direction, and by tightening the bolts the stop is held in a desired adjusted position. Rigidly secured on the beam 2 is a landwardly extending arm 74 having its free end 75 bent forwardly and adapted to operate as a stop for a purpose hereinafter explained. The tabular member 32 is provided at each end of its arcuate edge 76 with lugs 77 and 78 respectively, and on the plate 46, intermediate its pivot 47 and slot is a lug 7 9, and a similar lug 80 is on the plate 49.

As shown in Figure 2 the plow is down in o )erative position and the pinions 3t; and 37 are out of mesh with the gear 23, in other words the parts are in neutral and remain so until it is desired to raise the plow, an operation I will. now describe.

When it is desired to raise the plow a pull of the rod 67 will rock the ari'n 66 forwardly and the arm 62 downwardly, both of said arms being integral with. the sleeve (53 pivotally supported on the arm 27. l /ith the downward movement of the arm 82 the plate 46 is rocked on. its pivot through the link 61. hearing against the lower end of the slot. the plate rocks, the edg in contact with the end of the latch fil'presses the latch forward until it is disengaged from the central or neutral notch 25 in the p; t 24 of the bracnet 0. At this time the Z on and conseque y the further downward movement of the plate t6 rocks the member 32 on. its pivot During the movement of the parts just described the aris of the screw 31 is moving ii U rearward: of the pivot26 and the weigl-it; er the plowcompletesthebperatiori begun by the pull on tl1er0cl"67,.andj rocking-the member '32 sharply thepinion '37 thereon is n'ieshed-with'the gear 23011 the wheel 21.

The power required: -is suppliedby the traction of the wheel-521 and,-as thelatter rotates, is transmitted to raise the plow'by thege'a'r rotating the pinion 37 which' is in constant meslrwiththepinion 36'. The pinion 36 is rigidly mounted on the shaft-35g consequently"rotation'of the pinion'86 imparts a similar" motion to the bevel geared) which in turn actuate's the bevel pinion 43 on the lower end o i' the-screw 31'. As before stated, the screw 31 has a threaded "engage ment with the sleeve '30 pivotally' supported on the braoket29, andas the latter is rig idly 'i'nounted 'on the plowythe plow is'raised by eon't'inued'rrotation of the screw' 31, swinging the crank a'Xle' downwardly and-rear.- wardly until thejlug 80 on. the plate 49 con' tacts with the stop vcontinuingthis'movement of the crank "axle the pressure of the lug-', on thepla'te 49, against the'stop will swing the plate 49 so that'ithe' straight edge '6 thereof contacts with 'the'lu'g'77 on the member 32 swingingthe member- 32' on its pivot 26 and consequently removingthe pinion 37 from the gear 23, andas this occurs the latch engages with the central or neutral notch 25 in the part Ql ofthe'bracketc.locking the parts against movement and the plow in a raised position. a

' To lower the'plowthe rod '67 is pushed rearward'ly rocking thje'arm 66 in the same direction, and through the link 61 andthe arm '62 the plate 49 is rocked upwardly'on its pivot 5Ov until the straight'edge'ethereof is in contact with the h1g7? on the member 3'2 and the latch is disengaged from the cen tral or neutral notch'25 in part24 of the bracket 0. The member '32 rocks upward on its pivot 26 and moves the pinion 36 toward the gear. 23; at this time the axis of thescrew is moved forward -of the pivot 26 of the member 32 andthe weight'of theplow forces the pinion'36 and the'gear23 together, to operate the screw/"31 in a reverse direction to thatpreviously described; i-ls the plow descend's the crank a'z'i'le iocked forwardly and upwardlygjand' when the lug .79 presses against the stop 71 the plate 46' is rocked" on its pivot '47 untilftlre "straightjje'dge "cl; thereof operates against the ,lug7 8 on theinember swinging the T latter "diowiiwardaiid' moving the pinion 36 away' fronrthe gear 2-3 and I-ailowing the latch. to engage with the central" notch 25 in the part' 24 of the bracket 0."
